I2cdetect blank

I think my grove pi+ is broken out of the box. Green light comes on and my spotpear 3.2 lcd is working off of the grovepi pins but I Went through firmware updates and 12cdetect -y 1 shows grovepi not there.

Can you just keep the GrovePi+ connected to the Pi without the lcd and run the troubleshooting script for the GrovePi+ from here: https://www.youtube.com/watch?v=ZMadpIEYq5o and attach the log here. Can you also post a few good pictures of your setup and the GrovePi+ board.


I haven’t yet but I was going to just re write my image and go through the software steps again. Hoping that there is another way. The jumpers from analog ports are for an ADXL335.

Looks like the firmware on your Pi is not responding. Can you try running the firmware update following the directions from here: http://www.dexterindustries.com/GrovePi/get-started-with-the-grovepi/updating-firmware/ and let us know if that works. You should have a 0x04 on the I2C bus after this.

Also, there are a lot of accelerometers available on Grove System: http://www.seeedstudio.com/depot/s/accelerometer.html?search_in_description=0. Do have a look around and see if something suits your project.


Thank you for the help Karan. I tried to update the firmware but I get…
avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override this check.

also, after executing “firmware_update.sh” the red RST led on the grovepi lights up.
I am going to try and get this grove replaced. I think that grovepi is a great platform for beginners like me but maybe I just wasn’t lucky with the first one. I don’t know what else to do. Thank you again for the help. I will send you an update when my project is finished.

Really sorry for the bad experience with the GrovePi. You might have indeed got a bad board. While you are waiting for the replacement, it would great if you could run the troubleshooting script and paste the log on the forums, here are the directions: https://www.youtube.com/watch?v=ZMadpIEYq5o. This would help us in finding out the problem and help other people in the future too.

Also, do keep us updated about the project and also let us know if you need any more help.
